Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16912, here are decompositions:

11 + 16901 = 16912
23 + 16889 = 16912
29 + 16883 = 16912
41 + 16871 = 16912
83 + 16829 = 16912
89 + 16823 = 16912
101 + 16811 = 16912
149 + 16763 = 16912

Showing the first eight; more decompositions exist.
